For example, the device lacks a pre-leveling calibration mechanism, which leads to the problem that when the sheet metal is manually held and fed, the sheet metal is not placed horizontally and neatly, resulting in the sheet metal being easily irregularly bent and scrapped. In order to avoid such problems, a sheet metal bending device is proposed to solve the existing problems. Utility Model Content

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] See also Figure 1-4 The utility model provides a technical solution: a sheet metal bending device, comprising a mounting frame 1 and an electric telescopic rod 2, the electric telescopic rod 2 is fixedly arranged on the top of the inner cavity of the mounting frame 1, the bottom of the extended end of the electric telescopic rod 2 is fixedly connected with a pressing plate 3, and a bending slot frame 4 is fixedly connected between the two sides of the inner cavity of the mounting frame 1.
[0020] Furthermore, in order to facilitate the pre-calibration and placement of the sheet metal to avoid the problem of irregular bending and scrapping of the sheet metal, a servo motor 5 is slidably arranged on one side of the mounting frame 1, and the output shaft of the servo motor 5 is fixedly connected to a reciprocating screw 6 through a coupling, and the surface of the reciprocating screw 6 is rotatably connected to the front side of the pressure plate 3 through a bearing, and threaded sleeves 7 are threadedly connected to both sides of the surface of the reciprocating screw 6, and a pressure roller 8 is fixedly connected to the front side of the threaded sleeve 7, and calibration frames 9 used in conjunction with the pressure roller 8 are arranged on both sides of the front side of the bending groove frame 4, and a plurality of guide rollers 10 are rotatably arranged on one side of the calibration frame 9, and a rotating sleeve 23 is rotatably arranged on the surface of the pressure roller 8.
[0021] As a detailed explanation: in order to improve the reasonable applicability of the device, a sliding rod 11 is fixedly connected to the front side of the bending groove frame 4, and vertical sliding columns 12 are slidably connected to both sides of the surface of the sliding rod 11, and a limiting sliding sleeve 13 slidably adapted to the vertical sliding column 12 is fixedly connected to the front side of the threaded sleeve 7, and the bottom of the vertical sliding column 12 is fixedly connected to the mounting sleeve 14, and a telescopic block 15 is slidably connected inside the mounting sleeve 14, and one end of the telescopic block 15 is fixedly connected to the bottom of the adjacent calibration frame 9, and a reset spring 16 is fixedly connected between the adjacent telescopic blocks 15 and the mounting sleeve 14, a sliding groove 19 is opened on the front side of the pressure plate 3, and sliding blocks 20 are slidably connected to both sides of the inner cavity of the sliding groove 19, and the front sides of the adjacent sliding blocks 20 are fixedly connected to the rear side of the threaded sleeve 7, and a sliding groove plate 21 is fixedly connected to one side of the mounting frame 1, and a sliding block 22 is slidably connected inside the sliding groove plate 21, and the front side of the sliding block 22 is fixedly connected to the rear side of the servo motor 5.
